I have an M&W 400B like the one pictured. These work by operating a hydraulic pump. When you turn the load wheel, it begins to close a valve that restricts the oil flow and builds up pressure. If you load the tractor to its rated PTO speed, then you can read the horsepower directly off the gauge, since it is calibrated to convert pressure to horsepower at PTO speed. If, however, you want to check the horsepower at any other speed, then you have to read both the RPM gauge and the pressure gauge and line up those numbers on the side rule that comes with the dyno. The horsepower is then read from the slide rule.

The "horsepower gauge" on the dyno is only accurate at rated PTO speeds of 540, 720, or 1000. If you want to know the horsepower at higher or lower speeds than the standard PTO speeds, use the two gauge readings and consult the slide rule.

The water hose is for cooling the hot oil and it goes through a radiator inside the oil tank. The oil gets pretty hot when you have the load cranked down. There is a manual flow valve that lets you adjust the water flow to keep the oil temperature in a certain range.

The dyno should be hooked to your hitch for stability. Not only that, if you're cranking enough horsepower, the dyno can lift a wheel. We set a loader bucket on it to hold it down.

Today's Featured Article - A Farmall Story - by Ed Meadors. The year was 1978. Our young family had recently moved to rural Chesapeake, Virginia to a plot of land which would finally allow us to realize our dreams of a huge garden, critters and more lawn and pasture than we would ever use! We needed a TRACTOR; not a riding mower or tractor wannabe, but a real TRACTOR. The answer to our needs materialized in the form of a '44 Farmall A, complete with cultivators, discs, single plow, a 5ft.Woods belly mower and one, mounted spare 9.00x24 rear wheel. ...
